Add fprocess to generated CRDs and fix indentation

Indentation changed to four spaces when upgrading to the v3 YAML paser, this reverts to 2 spaces. The fprocess variable in the store was missing from generated function YAML files with faas-cli generate --from-store - this has now been fixed and an env will be emitted when there is no existing conflicting definition in the store's manifest. Tested before/after - env now can be deployed, previously it couldn't be. Signed-off-by: Alex Ellis (OpenFaaS Ltd) <alexellis2@gmail.com>
